One of these patients, aged 16 years with hypogonadism, had undescended testes and an AMH level of 0 ng/mL; one was in remission 1 year after chemotherapy for acute myeloid leukemia (AMH of 3.2 ng/mL); and one was post-surgery and radiation therapy for HNSCC (AMH of 0.82 ng/mL) (Table 2). Here, AMH is linked to head and neck squamous cell carcinoma.
